4 less (-4) 5 times a number (5n) is (=) 11 (11)
-4+5n=11
add 4 to both sides
4-4+5n=11+4
0+5n=15
5n=15
divide both sides by 5
5n/5=15/5
1n=3
n=3
the number is 3
The answer is 3y=1+2x
i say this because if the answer ain't telling you to solve for x the you just do this
-2x+3y=1
+2x =1+2x which all u have to do now is drop the positive 3y
which gives you 3y=1+2x
